Helps facilitate the removal of phosphate from aquaria during periods when dissolved organic material is abundant.

May be used on an ongoing basis to help control phosphate in heavily-stocked aquaria.

Over 50% stronger than most competing products.

Formulated by a marine scientist.

Technical Overview:Phosphate, while required in miniscule amounts by living organisms for proper functioning, can indirectly negatively impact the overall appearance of an aquarium system if it is allowed to exist at a concentration measurable by most aquarium test kits (e.g. >0.05 ppm); in order for this impact to occur, other undesirable substances must be present in varying concentrations, however these substances are rarely limiting in the typical marine aquarium. Because of this, elevated phosphate concentrations, whether sporadic or chronic, should be combated. Phosphat-E enables a quick solution to elevated phosphate concentrations by binding the reactive (“free”) form of the molecule and making it unavailable for biological uptake. The resultant inert phosphate compound (a particulate) may then be permanently removed from the system via mechanical filtration and/or protein skimming. This method of treatment may be used as needed and/or on a continual basis to maintain an immeasurable phosphate concentration in a marine aquarium.While Phosphat-E provides a workable solution to potential phosphate-related een as an alternative to proper and sensible aquarium husbandry. Aquaria with extremely-low to immeasurable reactive phosphate often appear more pristine than those in which phosphate is allowed to persist in an elevated concentration. Feeding aquarium inhabitants sensibly, limiting the use of organic-based supplements and additives, use of a high-quality synthetic aquarium salt blend, and performing water changes/replacing evaporation with purified water are all important aspects of phosphate control. Additional means of limiting phosphate are maintaining a culture of macroalgae in the system to naturally deplete phosphate and other substances, and/or the use of an effective and well-maintained protein skimmer.Notes: Phosphate test kits may show a false-positive reading after aquarium has been treated; this is a result of the chemical mechanism by which phosphate test kits operate and does not indicate that the product has failed to perform its intended function. The higher the percentage of bound phosphate removed by filtration, the more accurate test kit readings will be.

Instructions and Guidelines:Aquarium may become slightly cloudy when product is first applied; cloudiness is temporary and will dissipate. Read Notes on opposite panel regarding re-testing.Basic: Determine phosphate concentration in aquarium prior to first use by testing with an accurate test kit. Add product to aquarium near a mechanical filter or protein skimmer intake at the maximum rate of 5 ml (1 capful) per 20 US-gallons daily for each 1 ppm of phosphate present in system. When used in this fashion, 250 ml treats up to 1,000 US-gallons (3,785 L). Add weekly at same dosage to maintain an immeasurable reactive phosphate concentration.Advanced: Determine phosphate concentration in aquarium prior to first use by testing with an accurate test kit. Each ml of Brightwell Aquatics Phosphat-E will eliminate 1 ppm of reactive (available) phosphate in 4 US-gallons (15.142 L) of water. The result is an inert particulate that is permanently removed from the aquarium via mechanical filtration and protein skimming. To maximize the rate of phosphate removal, Phosphat-E should be added to the aquarium near the intake of a mechanical filter or protein skimmer. Doing so will enable the inert particulate phosphate compound to be effectively removed from the aquarium. Particulate material not removed by filtration will remain inert and the bound phosphate non-reactive indefinitely under normal aquarium conditions. The maximum dosage should not exceed 1 ml per 4 US-gallons (15.142 L) daily, as too rapid a decrease in the concentration of phosphate may irritate sensitive corals, particularly if the phosphate concentration has existed at a relatively-high level for an extended period of time (e.g. 3 - 6 weeks). The concentration of available phosphate in marine aquaria should not be allowed to exceed 0.05 ppm for any lengthy period of time; available phosphate in the presence of other substances can indirectly negatively impact the appearance of an otherwise beautiful marine aquarium. If corals or other invertebrates appear to react negatively to the addition of the product, it may be an indication that reactive phosphate is being removed too aggressively; decrease dosage by 50% and continue treatment until phosphate concentration appears to be immeasurable.

Caution:Harmful if swallowed. May cause eye or skin irritation. If in eyes, flush with water for 15 minutes, get medical attention. If on skin, wash thoroughly with water. Keep out of reach of children. Not for human consumption.

Comments:Was concerned that effect on corals and fish would be negative but this product works and works quickly. I am not sure what is in it but I can attest that I have seen no negative behavior in my fish and conversely my zoos and corals opened up more when I have used it.

Comments:It definitely works. The first day that I used it I added half of the recommended dose to the main tank. It did cloud the system as advertised. However, although it is "safe for all inhabitants....", some of my fish (two tangs and a marine betta) did have an adverse reaction by becoming very docile and less responsive. They did recover after a few hours when the cloudiness had cleared. Now when I use the product I isolate the main tank from the sump and add the Phosphate-E to the filter socks in the sump, maintaining circulation in the sump. Once the cloudiness has cleared from the sump I reestablish the normal circulation of the system.

Comments:This product does work, effectively and quickly. However there are some points to consider. Brightwell generally does not indicate what chemicals are in his products,claiming proprietary. Indications are that this product is some form of Lanthanum Chloride(LaCl), which is a popular anti-phosphate for keeping pools, spas and hot tubs clear of unwanted algae. With that being said LaCl binds the po4 and as stated on the bottle will remain bound inert and non-reactive indefinately under normal aquarium conditions. The key words here are "under normal conditions" The propertys of LaCl are such that when the ph drops below 6.8 the particulates will redessolve and allow the bound po4 to be released back into your system. Normally ph this low will not be encounterd, unless something else is drastically wrong, at which point po4 is the least of your worries. However with the use of a Co2 injected calcium reactor or a sulfur denitrator, the ph inside those units could drop below the 6.8. So if you use one of these units, you will have to be advised of their affects.

Comments:I was a little nervous about using this product but I followed the directions which were simple and added it into the intake of my HOB Skimmer. I did this in the evening and the water clouded a bit. By morning the water was cleared up and my phosphate test was about .03. I have a small setup at 36 gal. Fish, snails, coral were all fine. Watch for a drop in ph and add buffer after treatment. Tank looks great. I will continue to use this product along with monthly water changes.

Comments:The water gets really coudy when adding this stuff. I know it mentions this in the instructions but still. Also the ph drops about 0.1 right after I add this. I'm assuming it does remove phosphates (too soon to tell), but I think I will go back to using PhosGuard from Seachem with which I had great success.
